摘要
Mucin-producing bile duct tumors (MPBTs) are characterized by intraductal papillary tumorsproducing large amounts of mucin. The tumor comprises macroscopically prominent intraductal papillary neoplastic epithelia and produces a large amount of viscid mucin, resulting in dilatation of the bile ducts.1 These tumors of the peripheral bile duct, which include benign and malignant lesions, have also been referred to as intraductal growth- type peripheral cholangiocarcinomas,2 mucin-producing cholangiocellular carcinomas,3 intraductal papillary neoplasms (IPNs) of the biliary tract,4 IPNs of the liver,5 or IPNs of the bile duct.6 MPBTs have been the subject of recent attention due to its peculiar histopathology, biological and clinical behavior, varied radiological manifestations, and good prognosis of the patients] Due to the rarity of this disease entity and the non-specific clinical presentation, MPBTs are not well characterized. The purpose of this study was to define the precise diagnosis and correct management of MPBTs with the help of nine clinical cases observed in the last 10 years. The preoperative differential diagnosis, surgical procedure, and postoperative course of these nine cases were retrospectively reviewed.
